Cliffs:
Notice how the color of the right side has turned extremely light? That’s because of the higher amount of air trapped in the gear oil. Again, this is the full synth. Why’d this happen?, Ladies and gent’s, oil has antifoamant additives to reduce air bubbles. In this case, there was not enough Antifoamants to keep the oil from trapping air with Lucas added to it.
Also notice how the oil on the right has settled down to the bottom leaving very little on the gears. This is the PRIME REASON for not adding in additives into a already good designed oil/ lubricant.
